Thanks to the courtesy of Arseniy Kuznetsov, director of NetBeans, the winner(s) of the API Design Fest08 will receive a copy of "Practical API Design: Confessions of a Java Framework Architect" .
There will be a few rounds in the competition, during which the participants are supposed to solve tasks given to them in a timely manner. They should send their results to the API Fest 08 mailing list. The whole competition will use rules like those of the First API Design Fest.
hg clone http://source.apidesign.org/hg/apifest08/
You will get an Ant project in the currency directory. It is designed to be opened in NetBeans IDE easily, but it can also be manipulated from the command line or other tools by those who prefer pain over comfort.
Two sources files are important:
- currency/src/org/apidesign/apifest08/currency/Convertor.java - will contain the API that you should create. Feel free to introduce other classes, but please keep them within the org.apidesign.apifest08.currency package.
- currency/test/org/apidesign/apifest08/test/Task1Test.java - this is the class with actual tasks that your API has to fullfil. Please stuff the method bodies with code, so they demonstrate use of your API.
The project is currently not compilable (you need to make the Convertor class public somehow), compile it, compile its tests and execute the tests so they pass without a failure.
Remember that Runtime Aspects of APIs are as important as API signatures.
Finally zip your project and send it to the API Fest 08 mailing list by Friday, Sep 26, 2008!
zip -r $HOME/myname-task1.zip
We'll discuss your design decisions on Czech JUG session on Monday, Sep 29, 2008 together with announcement of the second task!
As processing of the results might take some time, we need to set the following rules:
- members of CZJUG takes precedence
- first come, first served
- if we run out of our capacity, we can stop processing further solutions
There will be multiple rounds each with new task. The goal is to finish the last round and select the winner by Oct 26, 2008 - that is the day of the NetBeans first release anniversary!
That is all, happy API designing!
